Re: OCR Software Recommendation
Most PC-based scanners come with OCR software. Even though my scanner is several years old, it still does the occaisional job for me and I've seen no reason to upgrade it. The Omnipage OCR software also works for the most part. When I try to OCR a newpaper or magazine article, I sometimes think it'd actually be easier / faster to just retype it. Now I don't know how it'd do in tabular or spreadsheet sources. Often those have tiny footnotes etc that can throw of character recognition.
A bigger question would be about maintaining columnar separation. If there's a blank in Column C, it might just move whatever is in Column D over. That is, omitting a cell entry that should be blank can be worse than failing to recognize.
But there's something else here. You indicated you intend to scan several hundred pages. This would be a huge job for a PC-based scanner to the point I'd say there's got to be a better way.
At work, we have high-volume scanners for insurance claim forms, and specialized OCR software that has to be adapted for each field. That's not home-based at all.
I'd really think hard about what you're trying to accomplish. Can it even be viewed online? WOuld cut-and-past from a web page be better, as onerous as that would be?
